应用

  • General-purpose switching and amplification
    • LED driving and signal routing Logic level conversion Load switching for low-power circuits

The BC846B from Nexperia is an NPN general-purpose bipolar junction transistor in an industry-standard SOT-23-3 surface mount package. The B group specifies a DC current gain (hFE) of 200 to 450 at IC=2mA, providing tighter gain distribution than the A group (110-220) or C group (420-800). The 65V VCEO and 100mA IC ratings cover a broad range of low-power switching and amplification applications. The 90 mV maximum VCE(sat) at 10mA indicates efficient switching with minimal voltage drop. The complementary PNP device (BC856B) enables push-pull and bridge circuit configurations. The BC846 series is one of the most widely used small-signal transistor families, available from multiple manufacturers with pin-compatible equivalents.

The BC846B is a planar epitaxial NPN bipolar junction transistor. The vertical structure consists of an N+ substrate (collector), N- epitaxial collector layer, P-type base diffused into the epitaxial layer, and N+ emitter diffused into the base. When forward base current flows, minority carriers (holes) are injected into the emitter, and the resulting collector current is amplified by the hFE gain (200-450 for B group). The 100 MHz transition frequency is the frequency at which the common-emitter current gain drops to unity, set by the base transit time and collector depletion capacitance. The 90 mV VCE(sat) represents the low saturation voltage when the transistor is driven hard into saturation (IB > IC/hFE). The SOT-23 package provides junction-to-ambient thermal resistance of approximately 500 K/W, limiting continuous dissipation to 250 mW at 25C ambient.
